Actually, CVS might be overkill. On one shared server, we use RCS to manage locking and rollback on config files. Locking is actually more important than rollback.
That depends on your situation. If there is only you working on a file then rollback is likely to be more important.
And isn't CVS just a wrapper for RCS?
But CVS can do what Eliot suggests but not within the editor.

Also, running 'rcsdiff <file>' tells you if there is currently a checked-out version, and what the differences are ...
diff is one of the most important tools in the open source world.
Without it, we would be struggling to check for changes that are bad or malicious.
